Okay, good point. But I wasn't talking about using a 4//3rds adapter, but a competitor to those cameras by Canon. i.e. could a lens built on spec to this patent be destined for a new Canon APS-C compact mount rather than EF-S, for example something like the Fuji X100 but with interchangeable lenses.

Could this be used on a m4/3 competitor for example, incorporating a fixed length lens but using a kind of digital zoom say 4/5 x?

Its a patent, not a product. Canon files thousands of them a year. Only a very few actually become products.

However, even if there were a adapter, it would not make much sense to mount it to a micro 4/3 camera, there would be no electrical connection, so the aperture would not work. Without control of the aperture, a lens is not going to work out well. It would be, of course, manual focus.
